Overview

The S252SMTB3 2-bay Thunderbolt enclosure enables you to connect two 2.5" SATA I/II/III hard drives (HDD) or solid state drives (SSD) to your Mac® or PC using an available Thunderbolt port.

Faster Transfer Speeds

Transfer data to and from your external drives faster than ever before, through a Thunderbolt connection. With data transfer speeds up to 10 Gbps, Thunderbolt performs 100% faster than USB 3.0 (5 Gbps), and 60% faster than eSATA (6Gbps). The unprecedented performance Thunderbolt offers makes this enclosure an ideal solution for high-resolution video editing and photography applications.

Connect Right out of the Box

To save you time and money, the S252SMTB3 includes a high-quality 1m Thunderbolt cable, ensuring you have everything you need for a hassle-free installation.

Excellent Drive Protection

To help ensure optimal operating temperatures for your hard drives and solid state drives, the Thunderbolt enclosure features a built-in fan and a durable, solid aluminum housing that maximizes heat dissipation.

Daisy Chain for Added Flexibility and Scalability

Get the most out of your Thunderbolt devices by leveraging the Thunderbolt daisy chain port. You can connect up to 6 additional devices such as monitors, docking stations, or additional external drives. This is an excellent docking storage solution for Ultrabooks or smaller more portable laptops that have fewer I/O ports.

The S25SMTB3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Frequently Asked Questions

Before You Buy

To determine if your hard drive will work in this enclosure, on the product page, click the Technical Specifications tab, and do the following:

  • Make sure that the enclosure supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the enclosure was tested with, the hard drive will likely still work with the enclosure.
  • Confirm that your hard drive uses the same interface type as the enclosure. For example, IDE, SATA, or M.2.
  • Make sure that the enclosure supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
  • Make sure that the enclosure supports the height of your hard drive. For example, 9 mm or 15 mm.
  • Verify that the power consumption of your hard drive doesn’t exceed the power output of the enclosure. If you’re using multiple hard drives, make sure that the combined power consumption of all of the hard drives doesn’t exceed the power output of the enclosure.

How to

To confirm that the Mac OS detects your USB device, complete the following:

  1. Click the Apple icon.
  2. Click About This Mac.
  3. Click More Info or System Report.
  4. Under the appropriate heading, confirm that your USB device is listed and that there isn't an error. For example, a network card would be under Ethernet Cards.

You may need to refresh the System Information page after you plug in your device.  To do so, press Command R with the System Information page open.

Your USB device is listed according to the name of the chipset. To determine the name of the chipset of your USB device, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Troubleshooting

When you troubleshoot issues with a hard drive enclosure, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Cables
  • Hard drives
  • Hard drive enclosure

To test your setup components, try the following:

  • Use the cables, hard drives, and hard drive enclosure in another setup to see if the problem is with the components or the setup.
  • Use a different cable, hard drive, and hard drive enclosure in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the hard drive and hard drive enclosure, it is recommended that you do the following:

  • To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
  • If the hard drive is listed with unallocated space, the hard drive needs to be reformatted. Right-click unallocated and click New Simple Volume. Follow the on-screen instructions to complete the reformatting.​

Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive.​

  • If the hard drive is listed as healthy but does not have a drive letter, for example, C:, right-click healthy and click Change Drive Letter and Paths. Click Add, assign a drive letter, and click OK.

Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.

(5 stars) Digital life in a box!

By:
I use this with Macintoshes - I have one large SSD containing OS and applications and home folders, and one large 72k spinner containing other data (photos, etc). I move this box, rather than a laptop, around from place to place, and though this occasionally results in licensing and activation issues, I feel happier with this as a solution than with a laptop.
